I am a teacher and along with another teacher (Batema) we pushed the whole IYA thing heavily. We did 10 or so observng nights, got more (previously there wasn't any) astronomy into years 8 and 9. We also got the school to pay for 5 days at Qld Astrofest (brilliant).
Not only did the whole school know about IYA but they are probably glad that is over.
Little do they know....we have plans for this year too.
I'd call it a success.
